I have 2 things in mind that will make weapon more accessible and add to its power fantasy.
1.Allow us to block with special action, like with Trollhammer torpedo from vermintide.
2.Make special action like on ogryns kickback.
It will give players more potent ways to defend themselves while carrying bolter.
Thus reducing need to swap and deal with long equip time.
Personally, i just really want to be able to “block jump” bosses attacks, with ranged weapon.
